Restaurant · Welwyn
Turning up here with small children shouldn't take much thought — there are high chairs, a kids' menu and step-free access, so a buggy and a toddler are both accounted for before you walk in. Free parking helps when you're unloading children and all their gear, and outdoor seating gives you somewhere to go if someone needs air or a wriggle. Gluten-free options are available if that's part of your family's picture. It tends to be lively rather than hushed, which usually means a bit of noise from your table won't stand out, and it's worth booking ahead.

A little something creative for your next meal out. Filled with colouring, simple drawing prompts for cute animals, origami and conversation starters designed to bring more play, laughter and connection to the table. 3 free printable packs for toddlers, preschoolers and primary-aged children.
